Ultimate 545

The Ultimate 545 is our answer for those who desire “Ultimate” sound but do not have the room for the larger Ultimate models. The Ultimate 545 is scaled down in size but not in performance, having exactly the same electronics as the larger models and employing the identical internal panel structural philosophy. The radiating area of the Ultimate 545 may be smaller, however the panels incorporate Bass-Focus® technology, bringing the bass performance very close to that of the larger models.

The space-age appearance of the U-545 along with the sturdy steel framework provide timeless beauty and superb sound.Black micro-texture Polane finish and black double-knit fabric are standard, however a wide range of finishes and grille fabrics are optionally available
